Application fi1ed November 8, 1914. Serial No. 870,584.

To all whom it may concern:

Be it known that I, THOMAS A. DoonnY, a citizen of the United States,residing at the city of St. Louis, State of Missouri, have invented acertain new and useful Improvement in Metallic Car Ends, of which thefollowing is a full, clear, and exact description, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, forming partofthis specification, in which Figure 1 is a front elevation of ametallic car end illustrating the'preferred form of my invention. Fig. 2is a side elevation of the same. Fig. 3 is a detail of a cross sectiontaken on line 33 of Fig. 1. Fig. 4 is a detail showing a verticalsection taken on line H of Fig. 3. Fig. 5 is a detail illustration of across section of a modified form. Fig. 6 is a detailshowing a verticalsection of said modification taken on line 6-6 of Fig. 5. Fig. 7 is adetail illustrating a cross section taken on line 77 of Fig. 1.

My invention relates to metallic car ends which are intended for use onbox cars, the same being designed as either a part of the originalconstruction of the car, or as a repair end which may be supplied toordinary box cars in which the end has been broken.

The purpose of the invention is to provide a very strong and stable endconstruction which may be manufactured and installed very economically,and which may be easily repaired.

In the use of metallic car ends, and particularly those forms in whichtransverse corrugations are provided so as to stiffen the endhorizontally, it has been observed that the metal is likely to failadjacent the corner posts or between the corner posts and the ends ofthe corrugations which terminate on or short of the corner posts. Thesefailures are due to the fact that a certain area of flat metal is leftat the ends of the corrugations for attachment to the corner posts orfor the formation of the inwardly turned flanges by which the sheetmetal is attached to the frame members of the car. Frequent failures arefound to occur at the point of junction of the sections, to preventwhich various expedients have been resorted to to reinforce thestructure at the line of junction, all of which increases the cost ofconstruction. It is my. purpose, therefore, tmprovide a form of car endconstruction Patented Dec. 19, 1916.

which is free from these various insufii- I ciencies, and this Iaccomplish by the provision of corner posts of special form and the useof sheet metal sections having corrugations which extend clear to themarginal extremities of the sheets andlwhich are secured to the cornerposts.

Referring now to Figs. 1, 2, 3, 4, and 7,

wherein the preferred form of my invention is illustrated, it will beunderstood that 1 represents the end sill of a car, 2 a side sill, and 4the longitudinal side framing members. I supply the corner post 5, whichis in'the form of a cast or pressed bar member, formed at its lowerextremity with the flanges 6 which are adapted for attachment to theunderframe members, and at its upper extremity with the-bracket 7 orsimilar portions which afford attachment for the side and roof framingmembers.

As will be seen in Fig. 3, the corner post is of general L-shape incross section, having the front member 8 and the side member 9. Thefront member 8 terminates in a sinuous flange 8, and the side member 9is provided with an inwardly directed sinuous flange 9. One or moresections of sheet metal 10 may be used. These sections are sinuouslycorrugated across their entire width, the corrugations being regular andon the same center. The corrugations may be formed in this sheet eitheras a part of the original rolling process, or they may be pressed coldinto this conformation. This is a signal advantage over the manufactureof corrugated sections in which the corrugations terminate short of theedges of the sheet, as it does not require reheating of the metal, andthe metal is not stretched, and consequently weakened, as is frequentlythe case when the metal is hot pressed into special shapes. The contourof the fiangesB and 9 is such as to conform to the outer and inner sidesrespectively of the sections 10,

there being a clearance between the conorder to compensate for anyinaccuracies in v the castin and to insure a close and snug.

joint. W en the sheet metal sections are placed in position, the flange9 laps behind the edge of the sheet metal, and the flange 8 lies uponthe outer side of the sheet metal, thus clamping the edge of thesection. The sheet metal is fastened to the flange 8 by rivets 11 whichare seated 1n the tops of the outwardly convexmg corrugations. Thisdisposes the heads of the, rivets on the inside of the car in theconcave corrugations, and being thus inset, there 1s no danger of theircomin in contact with the car 0, a very desira le arran ement especial yin the carrying of exp oslyes which might be discharged by concussionimparted to them by a rivet truck on the exterior of the car.

As will be seen from Figs. 3 and 4, the portion of the front member 8intermediate the flange 8 and side member 9, is slightly oflset'from theflange 8, thus providing a vertical channel 12 on the outside of thesection. This channel provides a runway for any water which might workthrough the joint between the flange '8 and the sheet metal. This waterwill flow downwardly and escape through a suitable opening at thebottom. This construction, therefore, protects the inner joint betweenthe inner flange 9 and the edge of .the section against weather, andforms a practically impervious 'oint. J In Figs. 5 and 6 is illustrateda modified form in which a sinuous liner plate or angle member 14 isemployedinstead of the flange 9. In this form, the sinuous flange 8,section 10, and liner plate-14 are all secured together by the rivets,and the front member is formed with a shoulder 15 against which theinner edge of the sheet metal abuts and upon which the edge of the linerplate lies, overlapping the edge of the sheet metal.

Where the different sections 10 are joined together, they are overlappedso that the marginal corrugations nest together and riveted through atthe top of an outwardly convexing corrugation. When the end is in place,the side sheathing of the car is suitably secured to the side member 9,as illustrated in Figs. 2 and 5.

This construction is equally adaptable to a car end in which thecorrugations are disposed "ertically instead of transversely. In thiscase, the marginal members of bar material, instead of being cornerposts will be formed as portions of the end sill and fascia, which willengage the corrugated top and bottom margins of the vertically disposedsections.

From the foregoing, it will be understood that this construction forms avery strong and very stable car end which will elfectively resist theWeaving movements of the car body, and which is free from Weak aaoaeaeareas. The continuous corrugations, extending as they do from margin tomargin of the sheet metal, and being secured to the specially formedmarginal members, provide a specially rigid and thoroughly reinforcedstructure.

I am aware that my invention may be incorporated in various formsotherthan those herein shown and described. Consequently, it is not myintention that my invention be limited to these specific forms, but thatit cover all other forms and other changes and modifications properlywithin its spirit and scope.
